Traditional Irish-style fish cakes with 30-second tartar sauce are a year-round dinnertime favorite at our house!

These are traditional, old fashioned fish cakes and they’re a great example of authentic Irish country cooking. Packed with tender flakes of just barely poached cod, lots of fork-mashed russet potatoes and a smattering of lemon, ketchup and parsley, they’re fried in a cast iron skillet until crispy golden on the outside, and downright feathery inside.
These fish cakes are homey and comforting for the winter months, but can be a light summer meal on top of a pile of fresh greens, — baby arugula is my ‘green’ of choice these days — along with plenty of lemon and tartar sauce. I’m giving you a twofer today, because the thick rich homemade 30 second tartar sauce could have been a post in itself. Trust me, you’re going to love me for it!
homemade tartar sauce ups the ante on these classic fish cakes
This homemade tartar sauce is simple, and wonderful, and I bet most of you assumed I was going to mix a few ingredients into a ready made mayo and call it homemade. But no, this is from scratch, made just the way my 30-second mayonnaise is made, with a room temperature egg and vegetable oil as its base. I add some dill pickles, capers, lemon, mustard, and some salt and pepper to the jar. It blends up instantaneously with my stick blender into a creamy tartar sauce.
TIP: Use a pasteurized egg for safety in the tartar sauce. You can usually find them next to the regular eggs in the grocery store.
it’s all about the fish-to-potato-ratio
While I usually make my fish cakes with a higher ratio of fish to other ingredients, in this case the potatoes and the cod face each other as equals. This makes for a cozy, satisfying dish which I don’t always associate with fish. The tarter sauce also helps this simple dish feel rich and hearty, and helps wake up the rest of the flavors.
These will keep well in the fridge and make great leftovers, you can reheat them in the skillet, (over low heat) or in the microwave. In fact these can be made from leftovers if you’ve got extra fish and potatoes around. Salmon would work well with this recipe, too.
tips and tricks for making fish cakes
I make fish cakes and crab cakes all the time, but I know they can be a little intimidating if you’ve never made something like this before. Here are some of my best tips for perfect fish cakes.
- Nearly all homemade seafood cakes like this are fairly delicate and need to be handled with care while cooking. The potato, egg, and cracker crumbs in this recipe all contribute to making a fairly sturdy mixture that should hold up well to frying, but you still need to use a delicate hand.
- A thin and flexible spatula will be your friend when flipping delicate fish cakes.
- Make sure your mixture isn’t too chunky — smaller pieces of fish and well-mashed potatoes will help hold everything together.
- Make sure to use a generous amount of oil in your pan to prevent the cakes from sticking, and give them enough time for form a golden brown crust on the bottom before attempting to flip them.

Ingredients
fish cakes
- 1 lb russet potatoes
- 1 lb cod fillet
- 1 Tbsp spicy ketchup or chili sauce
- a handful of minced fresh parsley
- juice of 1/2 lemon
- 2 large eggs, beaten
- 1/2 tsp each salt and fresh ground black pepper
- 32 Ritz crackers, finely crushed (use a small food processor or a rolling pin)
- several Tbsp vegetable oil for frying
garnish
- sliced green onion
- chopped parsley
tartar sauce
- 1 pasteurized egg, at room temperature
- 1 cup vegetable oil, at room temperature
- 1 tsp grainy Dijon mustard
- juice of 1/2 lemon
- 2 Tsp capers
- 1/2 cup dill pickles, chopped
- 1/4 tsp salt
- fresh cracked pepper to taste
Instructions
to make the fish cakes
- Peel and chop the potatoes into large chunks. Put them in a saucepan, cover with cold water, add 2 teaspoons of salt, and bring to a boil. Cook until the potatoes are very soft.
- Put the cod in a shallow saute pan and cover with cold water. Bring to a boil, and then cover, turn off the heat, and let the fish poach for about 10-15 minutes. Drain.
- Drain the potatoes and put them into a large mixing bowl. Use the back of a fork to mash them, leaving a little bit of texture.
- Add the ketchup, parsley, lemon juice, beaten eggs, and salt and pepper. Stir briefly to combine, and then add the fish, breaking it apart with your fingers as you add it. (Check for tiny bones as you do this.) Fold the fish into the mixture until everything is evenly incorporated. It will be fairly wet.
- I use a 1/3 cup measure to scoop out the mixture and form into patties. Flour your hands if necessary.
- Roll each patty in the Ritz cracker crumbs, to coat all surfaces and set on a platter. You can cover and refrigerate the cakes at this point for later cooking if you like.
- Coat the bottom of a skillet (I like cast iron) with vegetable oil and heat on medium heat until hot. Fry the cakes for about 5 minutes on each side until golden, crispy, and hot throughout. Note: the cakes will be very delicate, move and flip them with extra care.
- Serve immediately on top of a bed of greens. I like to mix the greens with a few chopped ripe tomatoes and some thinly sliced red onion. You can add a little oil and vinegar to the salad if you like before adding the cakes.
- Serve lots of fresh tartar sauce and lemon wedges on the side.
to make the tartar sauce
- Put all the ingredients into a jar that fits the head of your immersion blender. I find that a 16 oz wide mouth mason jar is the perfect size.
- Set the head of the blender down at the bottom of the jar, and turn it on. Blend for a few seconds and as the sauce starts to thicken, gently raise the blender up to blend all of the contents. This will only take a few seconds. you can pulse the blender a few times to continue to thicken the tartar sauce.
- Remove the blender, give the sauce a stir, and taste to adjust the seasoning. Screw the cap on the jar and keep refrigerated until needed. Use within a week to 10 days.

OMG, I need to make these fish cakes they look great, and there is nothing better than homemade tartar sauce! Fun recipes ๐
I have some great leftover delicious mashed potatoes..I’ll add salmon and that’s dinner.
Thanks! Not tonight..tomorrow..
Fun take on tartar!
I wish I would have been the one who ate the fish cake that’s missing in picture 4. They sound/look wonderful but I’m a bit ashamed to say that I’ve never made fish cakes. Never too late, right?
I do love you for this! Fish cakes are something I’ve been wanting to make for awhile. When I was in SAF every menu had fishcakes on them. For some reason you don’t see them much here and they are so good and there are so many varieties. Thanks, Sue!
I know what you mean, fish cakes aren’t on a ton of menus, but they should be! I do a lot of variations on the blog, and I’m always looking for new ones, it’s one of those recipes that’s a lot of fun to play around with…thanks for stopping by Abbe.
My gosh this sound’s wonderful!! I’m changing it up tho, just for today..I’ve some salmon left from dinner last nite my Irish mother may not approve but it’s worth the try. Fresh lettuce from my garden with a few grape tomatoes and your tartar sauce dinner should be heaven after work!!!!! Thank you
ooooh, now I’m feeling jealous…when we lived in New Hampshire our local fish shop had the most amazing salmon and potato pie…
This looks delicious! I’m going to make them today! What are pasteurized eggs? Can I substitute my natural, cage free, grain fed brown eggs? If not, then I would love to know the science behind it.
I love learning new things!
Pasteurized eggs are just heated very briefly to a high enough temperature to reduce any risk of food borne illness. I recommend them because regular eggs can, rarely, cause a problem if consumed raw. If you have your own eggs I think you’re fine to use them – and I’m jealous ๐
This is my kind of meal! I must try your quick tartar sauce.
Sue – this is speaking to me because you know I adore all things Irish, and fish, and potatoes, and that tartar sauce sounds fresh and wonderful. I still have not made my own mayonnaise but all these recipes sound perfect. Love these fish cakes – pinning and sharing!
Once you get started on the homemade mayo it’s hard to turn back. It’s like magic ๐
I love fish cakes and your 30 second tartar sauce sounds like the perfect choice!
